AUTOMATIC SHUT DOWN (ASD) RELAY TEST
NOTE: The following test procedures assume that the ignition system is functioning, and that a good spark is evident at the plugs. If this not the case
test the ignition system before proceeding with this test.
NOTE: Automatic Shut Down (ASD) relay operation may be tested with the use of the DRB II scanner or equivalent.
If no scanner is available proceed with the following test.
1.
Using a digital voltmeter connect the negative lead to ground and the positive lead to terminal 30 (red wire) of the ASD relay connector.
^
If battery voltage is present proceed to step 2.
^
If no voltage is present, check fusible links and supply voltage from the battery.
2.
Move the voltmeter positive lead to terminal 87 (GN/BK wire) of the ASD relay connector. Turn the ignition key to the START position and
